4 Claims.

eliminate accumulation of gummy substances and unburned particles of tobacco in the bottom of the bowl, adjacent thes'moke passage.

More specifically the invention embodies the provision of a metallic chain supported in the bowl of the pipe and having a portion thereof loosely placed in the bottom of the bowl and covering the smoke passage to serve as a strainer therefor as well as a ventilator to prevent the bowl from becoming too tightly packed with tobacco.

A further object is to provide a device of this character of simple and practical construction, which is eflicient and reliable in performance, relatively inexpensive to manufacture, and install in position and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction as more fully hereinafter described and claimed, reference being had to the accompanying drawings wherein like numerals refer to like parts throughout and in which:

Figure 1 is a fragmentary vertical sectional view through the bowl of a pipe showing the bowl cleaning attachment in position therein.

Figure 2 is a top plan view.

Figure 3 is a perspective view of the split retaining ring for one end of the chain.

Figure 4 is a fragmentary vertical sectional view through the ring on line 4--4 of Figure 3 show- K ing the manner of attaching the chain thereto.

Figure 5 is a fragmentary vertical sectional view illustrating a modified form of chain attaching ring and hook.

Figure 6 is a sectional view taken substantially on a line 66 of Figure 5.

Figure 7 is a perspective View of the attachment removed from the bowl of the pipe.

Figure 8 is a fragmentary vertical sectional view of a further modification for attaching the chain in the pipe.

Figure 9 is a top plan view thereof.

Figure 10 is a perspective view of the hook for the upper end of the chain.

Figure 11 is a similar view of an attaching washer for the lower end of the chain, and

Figure 12 is a fragmentary perspective view of the lower end of the chain showing a screw provided for attaching the same to the bottom of the bowl.

Referring now to the drawings in detail, and with particular reference to Figures 1 to 4., inclusive, the numeral designates the bowl of a smoking pipe having the stem 6 projecting from the lower portion thereof and in which the smoke passage 1 is formed communicating with the interior of the bowl adjacent its bottom portion.

The cleaning ataohment forming the subject matter of the present invention comprises a metallic chain 8 having a hook member 9 straddling the upper edge of the bowl and to the inner end of which the chain 8 is attached. As illustrated more clearly in Figure of the drawings, the inner end of the hook member 9 is formed with prongs I0 adapted to bite into the inner wall of the bowl, and the hook member 9 further is preferably constructed of spring material with its outer end ll tensionally bearing against the outer surface of the bowl and terminating in an outwardly inclined extremity I2 to provide a fingergrip for releasing the hook from the bowl.

The chain 8 is of sufficient length to enable a substantial portion thereof to be folded and lie loosely in the bottom of the bowl sufficient to cover the smoke passage 1 and the other end of the chain is attached to a split ring 13 having its ends pointed, as shown at I 4, and disposed in spaced relation as shown to advantage in Fig ure 3 of the drawings. The ring member I3 at a point diametrically opposite from its split ends, is formed with an opening IE to which the chain 8 is attached. The split ring I3 is also preferably constructed of spring material and adapted to be held in a compressed position in the bowl of the pipe immediately above the smoke passage l.

In the form of the invention illustrated in Figures 5 to '7, inclusive, the chain i6 is attached at its upper end to an eye I 1 formed on a wire hook or clip l8 which straddles the bowl IQ of the pipe, the inner end of the wire formin the .eye ll is provided with a pointed prong adapted for penetrating into the bowl. The outer end of the clip I8 is also formed into an eye 2| to provide a fingergrip for releasing the same from the bowl.

The lower end of the chain [6, in this form of the invention, is connected to an eye 22 formed at one side of a split wire ring 23 which also has its ends spaced apart and pointed, as shown at 24, the ring member 23 serving to retain the lower end of the chain in a position in the bowl immediately above the smoke passage 25 thereof.

In the form of the invention illustrated in Figures 8, 9, 10 and 12, the clip member 9 corresponds to the construction illustrated in Figures 1 and 2 of the drawings and the chain designated at 26 has its lower end attached to a screw 21 adapted to be screw-threaded into the bottom of the bowl.

In Figure 11 of the drawings, I have illustrated the manner in which the lower end of the chain 28 may be attached to a washer 29 having an opening 30 through which the screw 21 may be inserted for attaching the chain to the bottom of the bowl, as above explained.

From the foregoing it will be apparent that the folded section of the chain loosely positioned in the bottom of the bowl of the pipe will serve to collect the accumulation of gummy substance that usually collects in the bottom of a smoking pipe and may thus be removed'therefrom by the removal of the chain, together with any unburned particles of the tobacco remaining in the pipe. Likewise, the chain serves as a filter for the. smoke passage of the pipe as well as a ventilator by preventing the tight packing of the tobacco in the bowl, The split ring member l3 or 23 serves to scrape the bowl when withdrawing the ring 'therefrom.

It is believed the details of construction, advantages and manner of use of the device will be readily understood from the foregoing without further detailed explanation. 7

Having thus described the invention what I claim is:

1. A smoking pipe cleaner comprising a chain loosely positioned in the bowl of the pipe with a predetermined portion of the length of the chain resting in the bottom of the bowl, a hook member attached to one end of the chain and adapted to engage the upper edge of the bowl for suspending another portion of the chain in the bowl, a split wire ring adapted for frictional engagement in the bowl, and an eye on the ring for attaching the other end of the chain thereto.

2. A smoking pipe cleaner comprising a chain, means for attaching one end of the chain in the bowl of the pipe with an adjacent portion of the chain covering the bottom of the bowl to a depth above the smoke passag leading from the bowl, and means for suspending the other end of the chain from the upper edge of the bowl, the intermediate portion of the chain being free for movement into and out of the bowl upon movement of the bowlinto and out of emptying position.

3. A smoking pipe cleaner comprising a chain having its intermediate portion loosely position d in the bottom of the bowl of the pipe, means for attaching one end of the chain to the upper edge of the bowl, and a split ring frictionall'y' held against the walls of the bowl above its bottom 7 and having the other end of the chain attached thereto, said split ring constituting a scraper for the walls of the bowl during removal of the ring.

4. A smoking pipe'cleaner comprising a chain, and means at each end of the chain for attaching the ends respectively to the edge of the bowl of the pipe an d to the interior thereof with themtermediate portion of the chain loosely disposed in the bowl.
